im in high school last year a kid brought bomb making materials into school and they were found in his locker along with a list of names obviously he was expelled prior to this i had tried to befriend him i stopped when he was a physically abusive dick and was constantly making jokes that were just threats his old friends made an active effort to get away from him because he was such an asshole another friend of his was literally sliced by his with an xacto knife in class but for some reason never told a teacher my black friend who tried to talk to him got called a nigger and other racial insults its not the other kids fault when they have a violent classmate
